To all whom' it may concern:

Be it known that I, JAMES S. Annunws, ak citizen of the United States, residing at New York, in the county of NewYorl( and State ofNew- York, have invented 'new and useful Improvements in Underfrarnes lor Cars, of which the following is a. specification.

This inventionrelates to underfrarnes for railway Inthe accompanying drawings I have illustrated one embodiment of the invention and referring thereto Figure l is a topplan view of the underframe. Fig. 2 is a bottom plan view. Fig. 3 is an enlarged longitudinal sectional-view on the line'3`3 of Fig. 1. Fig. 4 is an enlarged transverse sectional view on the line 4 4 of Fig. 1.

the une 6 6 of Figi.

Referring to the drawings the side sills consist of two l The c'entral section 8 is also preferably made of cast steel in channel form to abut against the-ends ofthe end sections 7. Thefsections 7 and 8-of` the side sills are se.-

curely and rigidly fastened together by tie plates 9, 9- which overlap the adjacent ends of these sections and4 are riveted or bolted thereto.

The tie plate 9 (Fig. 5) is made-in channel form to fit in the, channel side of the side sill and the tie plate 9/ ismade flat and placed on bAt each end of the frame is a draw-bar sill 1 which is provided with an opening l1 to receive the draw-bar and its attachments. T he draiwbar sill is 'made of cast steel and lprovided with side projections 12 to abutagainst integral side pro-- jections 13 on the sections 7 of the side sills to form the body bolster'. -The draw-bar sill is also provided witli integral side projections 14' to abut against integral side projections 15 on the sections 7 of the side sills to 'forni tlreendsill. The draw-bar'sills are also provided with integrall side projections 16 which constitute parts of the center Ysill and abut against the cast steel intermediate section l7of the center sill. The projections 16 and the intermediate sections 17 of the center sill are made in -I-form and are securely and rigidly fastened together at their adjacent ends by over-lapping channel tie plates 18, 18 which are riveted or bolted to said sections (AFig. 6). The projections l2 and 13 are also made in I-form` and are securelyfastened together by channel plates in the same manner shown in Fig. 6.

Fig. 5 is a detail enlarged perspective view on the line 5 5 of Fig. 1. Fig. 6 is a similar view on` The pro- I j ections 14 and-15mn made in channel ,torni and are securely fastened together in the rnar-nier'shown inliig. 5. The projections l2 are provided with integral side bear- 60 ings 12." (Fig. 4). The transoins 19 are preferably made of channel iron and riveted or bolted at tlicir ends to iniegral lugs 20 on the side sills (Figfl) and similar lugs 20 I on the centerL and draw-.bar sills (Fig. El).

- The underframe is made 'almost entirely of steel cast- 65 ings and is strong and substantial in construction.

Y Many of the parts are duplicates and can be made with the same patterns which not only` reduces the cost ol" manufacture but also the cost of.repairing and replacement. The sections of the underframe are made so that they can be easily secured together in a strong and rigid manner and so that any section can be readily removed and repaired and replaced Without taking the entire frame apart.

What I claim and desire to secure 'by Letters Patent 75 is:

' 1. An under-frame lfor cnrs comprising .-1 metal side sill provided wiilr an integral projection extending' part-why between the side sill :rnd the dran/bar sill if constitute a part of thc end sill. v

2.
